DETAILED DESCRIPTION is a series of low dropout voltage and low power consumption regulator. Its application circuit is very simple, which only needs two outside capacitors. ADJUSTABLE OUTPUT VOLTAGE VERSION -ADJ provides a 1.25V reference voltage. Any output voltage between 1.25V~18V can be achievable by choosing two external resistors (schematic is shown below), R1 and R2 -ADJ Application Circuit of -ADJ The output voltage of adjustable version follows the equation: Vout=1.25 (1+R2 ignore IAdj because IAdj (about 15uA) is much less than the current of R1 (about 2~10mA). 1. To meet the minimum load current (>10mA) requirement, R1 is recommended to be 125ohm or lower. As -ADJ can keep itself stable at load current about 2mA, R1 is not allowed to be higher than 625ohm. 2. Using a bypass capacitor (CADJ) between the ADJ pin and ground can improve ripple rejection. This bypass capacitor prevents ripple from being amplified as the output voltage is increased. The impedance of CADJ should be less than R1 to prevent ripple from being amplified. As R1 is normally in the range of 100Ω~500Ω, the value of CADJ should satisfy this equation: 1/(2πfripple CADJ)<R1. VER 1.2 5
Explanation is a series of low dropout voltage and low power consumption regulator. Its application circuit is very simple, which only needs two outside capacitors. We have to take heat dissipation into great consideration when voltage of input is high. Because in such cases, the power dissipation consumed by is very large. uses SOT-89-3 package type and its thermal resistance is about 20 C/W. And the copper area of application board can affect the total thermal resistance. If copper area is 5cm*5cm (two sides), the resistance is about 30 C/W. So the total thermal resistance is about 20 C/W + 30 C/W. We can decrease total thermal resistance by increasing copper area in application board. When there is no good heat dissipation copper are in PCB, the total thermal resistance will be as high as 120 C/W, then the power dissipation of could allow on itself is less than 1W. And furthermore, will work at junction temperature higher than 125 C under such condition and no lifetime is guaranteed. Typical Performance Characteristics VER 1.2 6
